Fuel is Freedom

Who's making your fuel when the lights go out?

In times of war, natural disaster, PANDEMIC, grid down & national emergency people have turned to a little known technology called "wood gasification" to transform sticks and branches into clean gaseous fuel at home. The secret is a device called a wood gasifier.  


Going Off Grid? Got Wood?

Learn HOW to transform wood into motor fuel

Make free fuel gas at home in minutes using wood chunks from your own property, just like they did during WWII. Perfect for powering homesteads & remote locations. Survive grid outages & solar flares. Make fuel when none is available commercially.

“I would like to thank you so much for the plans. My generator started immediately the very first time!”

Byron

“This is the book you need if you want to build the gasifier on the cover. It's very, very, very well illustrated and is amazing in details. Even a newbie to wood gas can make one. ”

Jan

“I have built a couple small experimental gasifiers and have the first edition of this book. The author has put even more details in the second edition and hides nothing and has taken the mystery out of how they work and how to build one.”

Steve

“I am a red seal fabricator welder and I found this book informative and technically sound. However the format makes things understandable in such a way that even a non-trade person could make the final product happen.”

Jared

“The foremost complete and exhaustive expose on wood gasification. There isn't another writing as complete or definitive as this manual.”

P.T. Moore

New to Wood Gasification?

Watch this video series from 2014

During WWII 1 million gasifiers were created and placed into action to provide fuel when oil wasn't available, saving families and keeping their lives moving forward in a positive direction. That is the good news. The bad news is, many home built units failed from a lack of understanding and a rushed build. Despite the drum beats of war, these people didn't prepare in time. Those drums are beating again. Will you be ready?

FAQ

Answers to common questions

  • Contact/Purchase Questions?

    Purchasing questions: woodgas@gasifierplans.com

  • What size/type engine can I run?

    The design uses propane tanks and they are good for 500cc - 5.0 liter stationary internal combustion engines. Diesel engines can work with up to 75% wood gas/25% diesel. If you want to run bigger V-8 engines and fuel trucks, then use the hearth sizing chart and scale up the rest of the system to match using the bonus gasifier sketches.

  • Applications?

    With the information in this plan set and some ingenuity on your part, you can: run spark ignited generators, fuel older vehicles & gas tractors, heat greenhouses, pump well water, fire up kilns & forges, make activated charcoal for water purification, go off grid and much more!

  • Wood types? Run time?

    Wood chunks are mandatory because they make the best charcoal. The secret is in the charcoal chemistry. Use a table saw/ band saw to make them. No pellets, no hog fuel, no tires, no garbage, etc. Wood species does matter. Most work, but not all. Pine, fir and oak are good. Cedar is quite oily and cottonwood is too ashy. Test, test, test. The run time depends on how dense your wood is. The base reactor will hold a 40 minute load for initial testing. Add a hopper and get run times of several hours. Run a batch in the morning to charge batteries. Run again in the evening if needed. 24/7 is UNREALISTIC. Design your feed system around your wood type and energy needs.

  • How much does a wood gasifier cost to build?

    Bare bones, expect to spend $1200 - $1700. Using CNC parts, self built, expect to spend $2200 - $2700. Subcontract portions of your build and expect to spend around $4,000. Done for you turn-key, expect to spend $6500 in mild steel, $9000+ turn-key in stainless.

  • Can I build & sell gasifiers?

    If you build a gasifier and take the time to master your craft for 1 year, then you can build and sell your own design variation. You handle your own tech support. You don't use Ben's name or company in your marketing. You will only be successful if you teach and add value to the community. Solve new challenges and contribute to the wood gas lineage. If you are looking for a quick buck business opportunity, then don't bother, you will FAIL. There are no shortcuts in life. Read that twice!

  • Wood gas storage and energy conversion?

    You generally do not need to store gas. The gas is produced on demand by the suction of your engine or blower motor. You can bag the gas, but it's bulky. You can compress the gas into composite storage tanks or oxygen type tanks (1/4" thick), but don't put wood gas into air compressor tanks (1/8" thick) because the hydrogen can embrittle the metal over time and rupture your tank. Danger! The energy conversion is approximately 2.5 lbs of bone dry chunks into 1 kilowatt/hr of power in a 3600 rpm engine. 3 lbs per kw/hr at 1800 rpm.

  • Pitfalls/challenges?

    A poorly built/ low suction/ improperly tuned gasifier can produce tar. Tar occurs when wood oils aren't completely turned into wood gas and end up in the engine valve stems as creosote. When a gasifier is sized to the correct engine, using the charts in the book, then this isn't a problem. As a new user it is recommended you use an old engine to practice with while you learn the art of being a wood gas operator. Most youtube tinker projects are making oily gas. You get what you pay for.

  • Can you build a gasifier for me?

    Not usually, but if Ben is making a new book or there is enough cash demand to do a production run of 10 units, then it may be possible. Ben only builds stainless gasifiers. -- No grant funded projects please. Grant chasers window shopping with money they don't have is our #1 waste of time here. -- For a mild steel build, try Steve @ www.offgrid48.com and see if he has anything.
